Did you read the article? Whether or not the sound file embeds is dependant
on 2 factors - the file type & it's size.
File type: PowerPoint will only embed .wavs (you can fool it into thinking
.mp3s are wavs but let's ignore that for now). Not all sound files on the MS
website/clipart organiser are .wavs - for example I found some Christmas
songs that are .mids.
File size: the default setting in PowerPoint is to link any sound files
greater than 100kb, which is pretty small. You can change this in tools ->
options -> general -> link sound files with file size greater than... you can
push that up to 50000. You will then need to reinsert the sound file as this
is not retroactive.
So, is your file linked or embedded? Find the slide with the sound object on
it -> right click it -> edit sound object -> under 'information' does it say
[in presentation]? If it does it's embedded, if it doesn't it's linked. If
it's embedded all is good, if it isn't you need to send the sound file & the
presentation - you have to put them in a folder, zip it, send it and at the
other end they have to EXTRACT ALL FILES then play the presentation.
Complicated huh? That's why I always deal with .wavs where I can :-) If a
.wav isn't going to do it for you, have a look at the free pfcexpress:
Does that make it clearer?
